The backdrop of Gilgamesh is the fight against two opposing forces, one of the forces is known as the Gilgamesh lead by Terumichi Madoka (better known as Enkidu) and the other side is one led by The Countess of Werdenberg and the three Orga-Superior children who live with her. In appearance, the Orga-Superior are indistinguishable from humans. However, they carry a special power known as "Dynamis" which allows them to uses psychic energy and it allows them to control objects using only their mind. The overeaching theme of Gilgamesh is one of choosing sides.
